MAX9247ECM+T

The MAX9247ECM+T is a 27bit, 2.5MHz to 42MHz DC-balanced LVDS serializer in 48 pin LQFP package. The MAX9247 digital video parallel-to-serial converter serializes 27bits of parallel data into a serial-data stream. Eighteen bits of video data and 9 bits of control data are encoded and multiplexed onto the serial interface, reducing the serial-data rate. The data-enable input determines when the video or control data is serialized. The MAX9247 pairs with the MAX9248/MAX9250 deserializers to form a complete digital video serial link. Interconnect can be controlled-impedance PCB traces or twisted-pair cable. Data encoding reduces EMI and provides DC balance. DC balance allows AC coupling, providing isolation between the transmitting and receiving ends of the interface. The LVDS output is internally terminated with 100 ohm. For operating frequencies less than 35MHz, the MAX9247 can also pair with the MAX9218 deserializer.

• 3.3V core supply and features a separate input supply for interfacing to 1.8V to 3.3V logic levels
• Pre-emphasis improves eye diagram and signal integrity at the output
• Control data sent during video blanking
• Five control data inputs are single bit error tolerant
• Programmable phase-shifted LVDS signalling reduces EMI
• Output common-mode filter reduces EMI
• Greater than 10m STP cable drive, wide ±2% reference clock tolerance
• ISO 10605 and IEC 61000-4-2 level 4 ESD protection
• Operating temperature range from -40°C to +85°C
